Study Notes
Evacuated Tube System Overview
- A method for blood collection utilizing double-sided needles and a holder/adapter.
- Allows multiple specimen tubes to be filled and changed without blood leakage.
- Particularly beneficial when numerous laboratory tests are required for a patient.
Components of the System
- Consists of three essential components:
- Evacuated sample tube
- Double-pointed needle
- Special plastic adapter
Advantages of Multiple Blood Draws
- Enables blood sample collection using various tubes with a single needle insertion.
- Quicker than the traditional syringe and needle method, as blood flows directly from the vein to the evacuated tube.
Patient Identification
- First step in the blood drawing process involves identifying the patient.
- Patient identification divided into inpatient and outpatient categories.
- Inpatients: Confirm name and birth date, verify hospital bracelet name and number.
- Outpatients: Confirm name and birth date, verify requisition information.
Preparation Steps
- If a fasting sample is needed, inquire about the last time the patient ate.
- Explain the blood draw procedure to the patient for clarity and comfort.
- Apply a tourniquet 3-4 inches above the puncture site; it should not be overly tight or applied for more than 1 minute.
Vein Selection Process
- After preparing the site, the patient's arm should be positioned downwards, if possible.
- Select the vein while noting its location and direction.
- The tourniquet should be removed before cleaning the venipuncture site with a 70% isopropyl alcohol swab.
Cleaning the Site
- Clean the site in a circular motion, starting at the venipuncture site and moving outward.
- Finally, attach the ETS needle to the adapter to proceed with the blood collection process.
